Colouring rule.Connecting elements chain indicates the parent-child link relation of part.
Fig. 2 is the flow chart of the management method first embodiment of vehicle manufacturing BOM of the present invention, sees figure
1-2, in the present embodiment, management method comprises the following steps:
The variable quantity of information each in its low order BOM, according to certain cycle, is sent by S0, PDM system
To ERP system, to update the corresponding information in low order BOM of ERP system；
S1, ERP system generate the high-order BOM of this vehicle according to vehicle configuration order, and by high-order BOM
Being sent to PDM system, wherein, high-order BOM includes partly launching vehicle, half exhibition according to what calendar provided
Multiple full expansion vehicle that driving type is corresponding and each full expansion vehicle effective time in described calendar；
Wherein, described half expansion vehicle includes the basic configuration information of this vehicle；Described full expansion vehicle includes this car
All configuration informations within corresponding effective time；
Part in high-order BOM that S2, PDM system docking receives and its low order BOM uses condition
Carry out calculated crosswise, and combine effective time and the effective time of each full expansion vehicle of ground floor part,
Determine the ground floor Parts List of each full expansion vehicle；
The ground floor Parts List of the same half each full expansion vehicle launching vehicle is folded by S3, PDM system
Adding, to obtain bicycle low order BOM, bicycle low order BOM includes that this half expansion vehicle is in whole calendar
Ground floor Parts List；
Bicycle low order BOM that S4, PDM system-computed currently obtains and the last bicycle low order obtained
Measures of dispersion between BOM, and described measures of dispersion is sent to ERP system；
S5, ERP system update bicycle low order BOM of its storage according to described measures of dispersion；
S6, when receiving the manufacturing BOM solicited message of vehicle, the bicycle that ERP system stores according to it
Low order BOM determines this vehicle all of ground floor part, and according to the use rule of factory and part zero
The parent-child link relation of part chain instruction, selects corresponding sublayer part from connecting elements chain and is linked to this car
Ground floor part on, and be the color that part arranges correspondence according to color-match table, thus generate this car
Complete manufacturing BOM.
Seeing Fig. 3, in step so), PDM system is according to certain cycle, such as every day, by low order
In BOM, part master data, connecting elements chain, part use the variable quantity of condition and color-match table to send
To ERP system, to update the corresponding information in low order BOM of ERP system.Wherein, become when engineering
Time more, part master data changes, and now, the variable quantity of part master data is transferred to by PDM system
ERP system.When manufacturing change, connecting elements chain, part use condition and color-match table to change,
Now, the variable quantity of connecting elements chain, part are used condition and the change of color-match table by PDM system
Amount is transferred to ERP system.
In order to guarantee PDM system and the uniformity of ERP system data, by different " key "
The part master data variable quantity, the part that ensure ERP system correctly to process from PDM system to automatically deliver make
With condition and the variable quantity of color-match table, the variable quantity of connecting elements chain.When more new parts master data,
Guaranteeing that conforming " key " includes Part No. and part version number, now, step S0 includes following sub-step
Rapid: the Part No. of the part master data variable quantity that S01, ERP system automatic decision receive and part version
Number whether can mate in the part master data of low order BOM simultaneously；If S02 can mate, then simultaneously
The letter of corresponding part in the part master data of information covering low order BOM of use part master data variable quantity
Breath；If S03 cannot mate simultaneously, then in low order BOM, create this part master data variable quantity, and
Replicate the information of this part master data variable quantity.If it is to say, the part of change that ERP receives
The part master data sheet that is not present in ERP system of Part No. in, ERP system will create it and multiple
Make other property values all of this part；If the part master that this Part No. is present in ERP system
In tables of data, but the version number of this part is new, and ERP system then will create this version of this part and answers
Make other all properties values；If in the part master data sheet that this Part No. is present in ERP system and version
This number there is also, and ERP system has existed before being covered by this parts information being transmitted through by PDM system
Value.
When more new parts uses condition, it is ensured that conforming " key " includes father's part, sub-part, lookup
Number, initial change number and function code.Wherein, lookup number is a system property in PDM system,
For identifying a line BOM.Once certain row BOM is determined, then the lookup number following this row BOM will
Can not be changed again.Without this attribute, in view of the complexity of data, for special source data,
ERP system is that the data impossible correctly PDM system being transmitted through update in oneself system.Such as
For the two living data of row, research staff, designing engineering BOM when, may create two
The revolver of line number amount difference 1, in this case, if not utilizing the lookup number of PDM system, ERP
System will be about to another row with one and be override, and so may result in the situation that a revolver is lost, can give
Vehicle assembles and brings great risk when of production.On the other hand, it is considered to line numbers many in PDM system
Search number according to likely corresponding to one, thus must in conjunction with business attribute (such as father's Part No., sub-Part No.,
Function code etc.) determine that ERP system is by the replacement of data row and still increases newly, if PDM system passes
The property value of these combinations sent exists in ERP system, then ERP system is replaced and updates BOM
Data, if as long as these combination property values have one and ERP system variant, then ERP system is entered
Row increases newly and updates BOM data.Function code is for indicating part under vehicle in vehicle manufacturing BOM
Application function.
When more new parts uses condition, step S0 includes that following sub-step: S04, ERP system judge
Part uses father's part of condition variable quantity, sub-part, lookup number, initial change number and function code low
Whether the part use condition of rank BOM can mate simultaneously；If S05 can mate simultaneously, then use
The part that part uses the information of condition variable quantity to cover low order BOM uses the corresponding informance of condition；S06、
If cannot mate simultaneously, then in the part use condition of low order BOM, create part use condition variable quantity,
And replicate the information of part use condition variable quantity.It addition, the renewal of color-match table uses condition with part
Renewal together complete.
When update connecting elements chain time, it is ensured that conforming " key " include father's part, sub-part, search number,
Initial change number and function code.The step updated is particularly as follows: ERP system judges that connecting elements chain changes
Father's part of amount, sub-part, lookup number, initial change number and function code are at the part zero of low order BOM
Whether part chain can mate simultaneously；If can mate simultaneously, then the information of connecting elements chain variable quantity is used to cover
The corresponding informance of the connecting elements chain of lid low order BOM；If cannot mate, then in low order BOM simultaneously
Connecting elements chain creates connecting elements chain variable quantity, and replicates the information of connecting elements chain variable quantity.
In sum, about update mechanism, for different BOM data tables, if owning in key
Value can be matched in ERP system simultaneously, and the behavior of ERP system is that the data come with new biography are covered
Convering system has existed corresponding row data.Any difference of key will cause the newly created a line of ERP system,
And replicate data that new biography comes in this row.By using these keys, PDM system and ERP system
Data consistency be just guaranteed.By preparation clocked flip mechanism, it is achieved that PDM system-ERP
System from mobile interface, synchronize PDM system and the data of ERP system.
In step sl, throw in strategy and market survey according to research and development conditional policies, the market of company,
ERP system is according to obtaining the automobile type configuration order generation high-order BOM provided to client from market department, and presses
According to cycle regular hour, such as every day, the high-order BOM of generation is sent to PDM system.High-order
BOM is as shown in table 1, and high-order BOM includes partly launching vehicle according to what calendar was given, partly launching vehicle
Corresponding multiple full expansion vehicle and each full expansion vehicle effective time in described calendar.Wherein,
Half launches the short description that vehicle is vehicle configuration information, including the basic feature information of vehicle ordered by client,
The model of such as vehicle, internal configuration, color and engine type etc.；Full vehicle of launching is vehicle configuration letter
The long description of breath, including all characteristic informations of vehicle ordered by user, then indicates correspondence effective time
Full expansion vehicle effective initial time and end time in calendar.Sequence information includes car ordered by client
Basic feature information, such as, white automatically flap skylight and the X-type car of automatic air condition, ERP system
Unite based on to the prediction of user's order and consider that vehicle technical characteristic prepares the change occurred in time, according to
What calendar provided this vehicle configuration information partly launches vehicle (a kind of vehicle only one of which partly launch vehicle), root
Partly launch vehicle according to this, automatically generate standard-sized sheet car vehicle, and set up half expansion vehicle and all full expansion vehicles
Corresponding relation.
Table 1
See table 1, such as, in a certain order, user have subscribed two kinds of vehicles, is respectively and partly launches vehicle
1 and half launches vehicle 2, and half launches vehicle 1 and 2 is all given according to calendar, shares for 12 day in calendar
Phase, wherein, half launches vehicle 1 has three kinds of configurations M, N and P(the most partly to launch car within 12 dates
Type 1 is at date 1 to date 12 corresponding three kinds of full expansion vehicles M, N and P).Half launches vehicle 1 correspondence
The full effective time launching configuration M be the date 1 to 5, half launches the complete of vehicle 1 correspondence launches configuration N
Effective time be the date 5 to 9, the half full effective time launching configuration P launching vehicle 1 correspondence was 9
To infinity (last date can replace with infinity, it is also possible to directly uses last date).
Such as, half launches vehicle 1 and is configured to M, the obstacle physical prospecting used in configuration M in the date 1 to 5
Examining system is rearmounted radar, but in the date 5 to 9, detection system for obstacle becomes from rearmounted radar
Rearmounted radar and rearmounted video camera, corresponding, half configuration launching vehicle 1 becomes the feelings of N, P from M
Condition is by that analogy.Half launches the situation of vehicle 2 by that analogy.
As can be seen here, one and half expansion vehicles of vehicle may corresponding multiple full expansion vehicles.Use according to spy
Settled date is gone through the mode entirely launched and describes vehicle configuration information, is to a kind of rule of vehicle production in a period of time
Draw, have also contemplated that the differentiation of vehicle is to adapt to the large-scale scheduling of vehicle production that change is brought simultaneously.
See Fig. 4, in step s 2, the high-order BOM that PDM system docking receives launches car entirely
Part in type and super manufacturing BOM uses condition to carry out calculated crosswise, determines each full expansion vehicle
Ground floor Parts List.PDM system uses condition by the full vehicle configuration information launching vehicle and boolean
Crossing operation relation and the effective time of ground floor part of (i.e. part use condition) and entirely launch vehicle
Effective time, PDM system can select the ground floor part being suitable for this vehicle by automatical.
Owing to one and half launch vehicles and corresponding multiple different may entirely launch vehicle, therefore, in step S3
In, PDM system by the ground floor Parts List superposition of the same half each full expansion vehicle launching vehicle,
To obtain this half expansion vehicle ground floor Parts List in whole calendar, i.e. bicycle low order BOM.
In the present embodiment, step S3 includes following sub-step: S31, PDM system is according to effective time
Order from morning to night, is sequentially overlapped the ground floor Parts List of multiple full expansion vehicles, to obtain bicycle
Low order BOM, bicycle low order BOM includes that this half expansion vehicle ground floor part in whole calendar is clear
Single；In S32, PDM system correction bicycle low order BOM, ground floor part makes at the part of low order BOM
With time started of effective time in condition and end time.In sub-step S31, PDM system according to
Below equation superposition ground floor Parts List:
E=(A ∩ B)+(A-B) ∪ (B-A)
Wherein, E is stack result, and A is that the ground floor part of the full expansion vehicle in certain effective time is clear
The set of ground floor part or certain stack result in list, B is to be later than A and adjacent with A effective time
The full ground floor Parts List launching vehicle in the set of ground floor part.
Specifically, sub-step S32 includes following secondary sub-step: S321, for the ground floor in A-B
Part, if the end time of its effective time in low order BOM be later than and entirely launch car corresponding to B
The time started of the effective time of type, then revise end time of this ground floor part effective time for corresponding to
The time started of the full effective time launching vehicle of B；S322, for ground floor part in B-A, as
Really the time started of its effective time in low order BOM launches the effective of vehicle early than corresponding to the complete of B
The time started of time, then the time started of the effective time revising this ground floor part is corresponding to B's
The time started of the full effective time launching vehicle.
Seeing table 1 and Fig. 5, as a example by half expansion vehicle 1, it launches vehicle according to effective time entirely from early
Order to evening is arranged as M, N, P.Ground floor zero in the full ground floor Parts List launching vehicle M
The collection of part is combined into A, and in the full ground floor Parts List launching vehicle N, the collection of ground floor part is combined into B,
In the full ground floor Parts List launching vehicle P, the collection of ground floor part is combined into C.In sub-step S31,
First superposition A and B, stack result is E, E=(A ∩ B)+(A-B) ∪ (B-A).Then by E
Superposing with C, stack result is F, F=(E ∩ C)+(E-C) ∪ (C-E).The superposition finally given
Result F is the half expansion vehicle 1 ground floor Parts List in whole calendar (in date 1-12).For
Accurately and correctly apply the use time of ground floor part under specific vehicle, in sub-step S32,
Opening of effective time that needs to revise ground floor part in stack result in the part use condition of low order BOM
Time beginning and end time.Such as, in A, comprise ground floor part X(assume that X is in low order BOM
In effective end time be the date 8, date 8 is more than the date 5), B does not comprise X, A and B superposition
After, it is the date 1 to 9 that stack result launches vehicle 1 effective time corresponding to half, if not revising, and the knot of X
The bundle time is still that the date 8, and X is this car inapplicable on date 5 to the date 8 in fact.Therefore, for
Adapt to X and launch the vehicle 1 application in different time half, need to use the opening of effective time of N
The end time of time beginning modified chi.In like manner, need to repair the time started of ground floor part in B-A
It it is being just the time started of effective time corresponding for N.
In step s 4, PDM system transfers last bicycle low order BOM that calculates from interim table, and
It is compared with this bicycle low order BOM obtained, calculates both measuress of dispersion, and revise difference
Measure the effective time in low order BOM, measures of dispersion is sent to ERP system.Seeing Fig. 6, this obtains
Bicycle low order BOM obtained is corresponding to the half expansion vehicle M low order in calendar (D～∞) calculated today
The ground floor Parts List J of BOM, last bicycle low order BOM calculated is corresponding to calculating yesterday
And it is stored in PDM system half expansion vehicle M ground floor of low order BOM in calendar (D '～∞)
Parts List I, calculates measures of dispersion G:G of new and old bicycle low order BOM according to below equation
=(I-J)∪(J-I).If in I-J, the end time of the effective time of ground floor part is more than D, then by PDM
In the part use condition of low order BOM of system, the end time of the effective time of this ground floor part is revised
For D.If in J-I, the time started of the effective time of ground floor part is less than D, then by PDM system
Low order BOM part use condition in time started of effective time of this ground floor part be modified to
D.The above-mentioned variable quantity of low order BOM in PDM system, can be according to certain cycle, such as every day, more
In new low order BOM in ERP system.
In step s 5, ERP system updates it according to the measures of dispersion of bicycle low order BOM received and deposits
Bicycle low order BOM of storage.In the present embodiment, it is achieved the key that bicycle low order BOM updates is father zero
Part, sub-part, search number, initial change number and function code, step S5 include following sub-step: S51,
